My contractor painted the exterior grade wood with 2 layers of Kilz2 primer, and then 2 layers of Behr interior grade black enamel.
I've decided to change the color to white (for lighting reasons) so I figured to go with Behr's interior/exterior grade enamel for the added protection...
I know to do some sanding first, then add a Shellac primer, and then the new enamel paint. Are these the correct steps?
Will I have any issues down the road with peeling/cracking if I do this? I know there are other products I could've used (marine grade paint, etc) but the wife is pregnant and I wanted to stay safe. I'd rather not have to strip the entire thing and re-paint.
Thanks for any and all recommendations.
